Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wallboard auxiliary positioning, and particularly relates to a flow-guiding wind-resistant composite support structure for photovoltaic buildings. BACKGROUND

[0002] With the growing global demand for sustainable energy, solar photovoltaic power generation technology has become an important part of energy transformation. Photovoltaic power generation systems usually convert solar energy into electricity by installing photovoltaic components on specially designed supports. These photovoltaic support systems are widely used in various building roofs, ground and water surface scenarios, especially in the field of building integrated photovoltaic (BIPV), which has a broader application prospect.

[0003] However, in practical applications, photovoltaic support structures face many challenges. Among them, wind load and vibration are key factors affecting the safe and stable operation of photovoltaic systems. In strong wind environment, photovoltaic panels and support structures may produce significant vibration and even deformation, which not only reduces power generation efficiency, but also causes structural fatigue damage, shortens system service life, and in extreme cases, even causes structural damage and safety accidents. Conventional fixed photovoltaic supports or simple adjustable supports often have difficulty in effectively responding to complex and variable weather conditions, especially sudden gusts and vortices, and their wind resistance and vibration reduction performance are obviously insufficient.

[0004] In the current technology, although there are some solutions to enhance the wind resistance and vibration reduction performance of photovoltaic support structures, such as increasing structural strength, optimizing structural shape or using passive damping dampers. However, these methods usually have their limitations. Simply increasing structural strength will lead to increased material costs and construction difficulty; passive damping devices have limited effect in dealing with vibrations of various frequencies and amplitudes, and cannot actively adapt to environmental changes.

[0076] The unique pneumatic stability enhancement mechanism, including an adjustable lifting bottom plate assembly and a pressure difference guiding assembly, can actively guide airflow, making the airflow speed below the photovoltaic bearing platform greater than that above, thereby generating a downward pneumatic force. This principle, similar to the "grip" of a racing car, effectively counteracts the upward lifting force generated by strong winds on the photovoltaic platform, greatly enhancing the anti-overturning stability and overall safety of the photovoltaic system under extreme wind load conditions. In addition, the tail wing biomimetic adjustment assembly set at the high end can automatically adjust the angle under high wind speed, further simulating the function of a racing car tail wing to provide additional pneumatic downward force, providing double protection for the safe operation of the system under super strong wind.

[0077] The vertical damping assembly, the first circumferential assembly, and the second circumferential assembly are integrated into the support module, forming a comprehensive composite damping system. The pneumatic damping unit provides vertical buffering and stability, and the circumferential spring and the abutting damping arm absorb and dissipate the vibration energy in the horizontal and torsional directions, effectively suppressing resonance and fatigue damage caused by wind-induced vibration, ground vibration, and other external loads on the photovoltaic structure. This multi-directional and multi-level damping capability significantly improves the durability of the photovoltaic components and the support, greatly extending the service life of the entire photovoltaic system.

[0078] The central control system introduced by the present application is one of its core advantages. This system can obtain environmental parameters and structural state data in real time, and intelligently coordinate the damping mechanism and the aerodynamic stability enhancement mechanism according to the preset control algorithm. For example, when the wind speed suddenly increases, the control system can simultaneously instruct the aerodynamic stability enhancement mechanism to increase the downward pressure and adjust the damping characteristics of the damping mechanism to optimally cope with wind load. This active and intelligent adaptive regulation capability ensures that the photovoltaic system always maintains the best operating state and the highest safety under various complex and variable weather conditions.

[0079] The strong "grip" provided by the aerodynamic stability enhancement of the present application enables the photovoltaic bearing platform to maintain a more stable posture and inclination angle under strong winds, reducing shaking and deformation, thereby ensuring the optimal light receiving angle of the photovoltaic panels and effectively maintaining or improving power generation efficiency. At the same time, the efficient composite damping function reduces the damage of mechanical stress to photovoltaic components. In addition, the lifting sealing unit, especially the PVC transparent side plate and the crosswind flow guiding component in the second sealing unit, not only prevents turbulent interference, but also facilitates the exhaust work between the roof and the bottom plate, and between the bottom plate and the platform, effectively avoiding corrosion caused by water accumulation and moisture, further improving the long-term reliability of the system and reducing maintenance costs.

[0080] The present application has made many optimizations in structural details, embodying good practicality and maintainability. For example, the detachable connection of the lifting base plate using splicing flanges and splicing grooves, as well as the locking pieces in the support module, greatly simplify the on-site installation, disassembly and later maintenance work of the system. The self-lubricating bearing and flexible protective sleeve at the hinge component further improve the durability of the mechanism, significantly reducing the comprehensive cost of operation and maintenance.
